JIRA RESTful call for issue details

The result of the query only includes the first 30 days of the work logs. I want ALL of the work logs. I do not see a parameter to control this. Am I looking at the wrong docs? Or, is there some other way to control the amount of data returned in the work logs?

...It's true that there are projects in Jira; but they are merely a way to cut off issues, to tell them apart from other sections of work and to apply rules that are specific to that team (the schemes)....
